hello guys,
i'v been looking for the correct battery offset values for the 560cc pink top feed injectors, but on my searches i found about 3 different offset scales for the 560cc's, can anyone please post the correct scale?

thanks alot!

 

According to my accessport maps for 2005 STi the battery voltage offsets are as follows:

6v 4.9
9v 1.723
12v 0.875
14v 0.67
16v 0.48

But you might need different values on a Honda. The Denso 550cc offsets should run pretty good.

 

Its pretty easy to tune the offsets too as I find the published offsets are sometimes incorrect. You tune your idle AFR using the published 14v offset values. Then unplug the alternator or take the belt off so now the engine is running off battery alone. And just adjust the offset at 12v and 10v as voltage drops over time to achieve the original idle AFR. Usually from there you can interpolate those data points.

 

Yeah, nothing can beat real data testing.

 

Even though that's how I explain how to tune it in my manual, you're never really pulsing at 12v. At cranking you're between 9-10v, and immediately after post-start dump you're above 13.5v.
If it was a linear scale then it would be ideal to get two points of data so you could calculate the other cells, but cranking and post-start conditions are pretty much static regardless of the battery offsets.
As long as you use the denso presets and tune idle offset you should be pretty damn close.

 

Yes, this is very true.
